Worcester, Mass. — Allegro MicroSystems Inc. has introduced a full-bridge motor driver designed to drive low-voltage bipolar brushless DC motors. This fully integrated single-chip A1442 motor driver ...

Abstract: High-precision commutation is an important factor to ensure the high-efficiency operation and smooth torque performance of the brushless DC motor (BLDCM ...

DC motors are widely used in industrial automation, household appliances, and other fields; however, the electromagnetic interference (EMI) generated during their operation may affect the normal ...

Abstract: In medium and high voltage DC power systems, traditional forced commutation breaking technology has the problem of breaking failure due to heavy breakdown after arc current crosses zero when ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...
